HT 383 383CI PARTIAL ENGINE BLOCK

P/N 12499106 [Old P/N 12498332]      What a great starting point to build your own hot rod 383 engine. The only major items you will need to complete your engine are cam, lifters, cylinder heads, and manifold.      This 383 ci partial engine is used on all 383 crate engines. The partial engine includes the following items: P/N 88962516 - Block, 383 stroker after machining - 1 P/N 12489436 - Crankshaft, 383 stroker - 1 P/N 12499102 - Bearing standard front and intermediate - 4 P/N 10120993 - Bearing standard rear - 1 P/N 12499108 - Bearing standard connecting rod - 8 P/N 14088784 - Sprocket, crankshaft - 1 P/N 14088765 - Flexplate assembly - 1 P/N 12497624 - Rod, connecting single 383 - 8 P/N 12499103 - High Silicon Aluminum .005 O/S - 8 P/N 12499107 - Ring Kit, .005 O/S - 8 P/N 12555283 - Pump assembly, oil - 1 P/N 12550042 - Pump assembly (screen) - 1 P/N 03764552 - Shaft, oil pump drive - 1 P/N 12557558 - Pan assembly, oil - 1 P/N 10108676 - Gasket, oil pan - 1 P/N 12562818 - Cover, front timing (plastic)- 1 P/N 12498008 - Balancer - 1      The partial engine does not include camshaft, lifters, timing chain or cam sprocket. The oil pan is loosely assembled on the block. So it can be disassembled without destroying the pan gasket. In 2004 GM redesigned the pistons and rings and they are .005" over sized now. This was done to better improve piston to cylinder wall clearance. The .005” O/S pistons and rings are the recommended standard size for all second design 383 ci engines. The first design ring and piston sets were: [Rings - 12522848 std. 4.00”, Pistons - 12489437 std. 4.00" (piston & pin set).] Note: The partial engine blocks we have received from GM so far have also come with an oil dipstick, an oil filter, and an information sheet.
